15 Claims.

"This invention relates to a bale tie and more -particularly to va tie element including improved cooperating portions for forming an interlocking arrangement, whereby the ends of a tie are securely held together.

An object of this invention is the provision of an improved bale tie including means whereby the parts are restrained from accidental disengagement'in case the tie should become slack.

A further object is the provision of an improved tie, the parts of which will be restrained from axial movement, of any substantial amount, .by'reason of frictional binding action between vthe parts thereby preventing movement of the parts sufliciently to permit their disengagement by'i'elative angular movement. f Other objects and advantages of this invenition will become'apparent from the following detailed description of the same.

As shown on the drawing: y

For'l the purposeof illustration I have shown in the drawing a bale tie 5 `applied to `a bale of cotton'or the like 4 illustrated in phantom.v The tie 5 has iormed'int'egral therewith two tie ends 6 and '7 respectively which are formedv in a manner to interlock and cooperate with each other to prevent accidental disengagement thereof. The tie end 6 ispreferably in the form of atriangle, the apex Sib'eing on the longitudinal axis of the tie, with the sides 9 and ldverging therefrom to points substantially spaced from the longitudinal axis and rbeing connected togetherv by a base portion 11 which is deformed intermediate its ends in a manner to engage between the diverging portions 13 and 14 of the hook member on the end 7. A Yhook portion orbight 15, connecting the ends of the diverging portions 13 .and 14 extends a greater distance at right angles to the longitudinal axis of the tie, thanv does the base portion 11 of the tie end 6, andthe width of the hook portion at the lplace of bending indicated at 16 is such that -a slight -amount of longitudinal movement of the tie ends toward each other causes a binding engagement between the side portions 9 and 10 on rthe triangular loop and portions 1'7 and 18 respectively, in addition tothe binding engagement between the deformed portion 11 on the loop 6 and the diverging portions 13and 14 between which it is disposed. The bight 15 also has its central -portion Ideformed in the same direction as is the central portion of vthe base 11, to restrictthe passageway o f the base 11 in its disengaging movement as illustrated in Figure 4; 1 `In Figures 5 and 6 the bight portionpf lthe hook is ofv modified construction in that a deformation or corrugation in the end ofthe hook extends outwardly from the axis of the tie as indicated at'25, instead of `inwardly as in Figure 3. p i i- In Figures 7 and 8 is shown anothermodifloation of this` inventionein which the ends Gand 7 are lof a somewhat simpler form. The loop6 includes the diverging elements 9 and10- anda base portion V31 which is in a plane with the diverging portions 9 and 10. The hook end '7 comprisesa bi'ght portion 32 formedfrom the base anddivergingv side 33 of a triangular loop.v I-n this form ofthe inventionfthe bightV 32is wider than the base 31 of the loop, 6].such that it is necessary to rotate one vend relative to the other before .the same may-becomedisengaged.

In the use of this inventio-nitwill .be understood from .an inspection of Figure -1 that. the bightptthe vhook end is normally disposed adjacent the bale such that pressure from the bale will? normally urge the'bight toward the `axis-of the tie and further restrict the pathway of movement of thetie ends toward each other,'thereby insuring -asecure tie and'- .effectively preventing accidental disengagement. r l

It will -be-understood from the-foregoing description, together with the accompanying drawv,ing that this invention is susceptible of various modifications without Vdeparting from fthe prin- I angle being widest at the base, a hook on the other said tie end including a return bent bight, said hook being wider at the end of the bight than is said loop at the base.
